Expanding exponentials

The exponential function applied to a sum can be converted into a product of exponentials; namely,

e^x+y=e^xe^y.

The expexpand command does this conversion. For expansions in other bases, see Section 10.3.6.

expexpand takes expr, an expression.
expexpand(expr) returns the expression expr with exponentials (base e) of sums rewritten as products of exponentials.
